i have made a little example:
Here i have a simple material function which has 3 outputs.
Here i have a simple post process material which just use the multiply output.
My question is: does the add and substract functionality still be used from the GPU in this case?
The reason why i ask is: I have a complex pp material and i wanna create a quite complex material function to clean the pp material up.
But i will call the material function a few times and i do not need all outputs every time. Just wanna know if i can put everything in one function and do not have to worry about unused calculations.
Thanks in advance
